www/angie-module-auth-totp: New port: TOTP authentication for angie

The nginx-http-auth-totp module provides TOTP authentication for an
Angie server.

The Time-based One-Time Password (TOTP) algorithm, provides a secure
mechanism for short-lived one-time password values, which are desirable
for enhanced security. This algorithm can be used across a wide range of
network applications ranging from remote Virtual Private Network (VPN)
access, Wi-Fi network logon to transaction-orientated Web applications.
